A Candle in the Dark.

A series of "vampire" style murders on campus has Sarah scared of her own shadow - It doesn't help that her new dorm mate Lilith wears only gothic clothing, is afraid of crosses, avoids daylight and resembles a member of the undead. Sarah becomes convinced that Lilith has something to do with the horrendous murders. When Sarah can't convince others of her outlandish theory...she becomes the next target.
